FILM FOR MOVING PICTURES.

Specification of Letters Patent.

Patented Dec.12,1911.

Application filed August 15, 1911. Serial No. 644,115.

a citizen of the United States, residing at New York city, county andState of New York, have invented a new and Improved Film for MovingPictures, of which the following is a specification.

With films as heretofore generally made,

I the display of the last picture on the film representing the end of adrama or other matter presented, was followed by an instantaneousdarkening of the screen. In this way, the display which held the s e0tators attention was so abruptly out o as to impart a shock or a feelingof dissatisfaction, the same as would be the case were the actors on astage after sayingthe last word suddenly wrapped into darkness insteadof being gradually withdrawn from the audience either by their leisurelyexit or by the slow lowering of the curtain.

My invention relates to a film in. which this abrupt transition of lightto darkness is obviated, so that a pleasant finale is obtained. 4 Y

Thedrawing represents the end portion of a film embodying my invention.

In carrying out my invention, the film A is provided with the usualseries of pietures 10, 11, 12, etc., illustrating the suc; cessivephases of a story, or other matter. The last picture of the series whichshows the finale or last pose of the characters, etc., is reproducedasuitable number of times'as at 12, 12?, 12, etc. All of thesereproductions are identical in contour, but each image is printedsomewhat darker than the preceding image, the last image 12* beingfollowed by a field B, which is substantially black. Thus when the filmis displayed, the final scene will linger before the spectators eyes forsome time, and will while being exposed assume a gradually darkeningtone that eventually goes over into black. In this way the subjectmatter of the last scene presented will be impressed upon the audienceand by graduallyvanishing from sight will avoid the objectionable abrupttransition above spokenof. In the manufacture of the films, the gradualdarkening of the successive copies of the last picture may be obtainedby reproducing it the desired number of times, while thelight-controlling diaphra' is gradually closed or the power of the lightis gradually reduced. It is obvious that the efi'ect of graduallywithdrawing the last picture from view may also be obtained by havingthe successive reproductions thereof made lighter instead of darker. Inthis case the last picture will be made to dissolve gradually into awhite blank field 2. A film for motion pictures provided with a seriesof prints representing consecutive phases, a last rint of said series,and a plurality of repro uctions of said last print directly succeedingthe same, said reproductions being successively printed in darkershades, to gradually merge into a black field.
